Summary
The Sophos Web Appliance Remote / Secure Web Gateway server (version 4.2.1.3) is vulnerable to a Remote Command Injection vulnerability in its web administrative interface. These vulnerabilities occur in MgrDiagnosticTools.php (/controllers/MgrDiagnosticTools.php), in the component responsible for performing diagnostic tests with the UNIX wget utility. The application doesn't properly escape the information passed in the 'url' variable before calling the executeCommand class function ($this->dtObj->executeCommand). This function calls exec() with unsanitized user input allowing for remote command injection. The page that contains the vulnerabilities, /controllers/MgrDiagnosticTools.php, is accessed by a built-in command answered by the administrative interface. The command that calls to that vulnerable page (passed in the 'section' parameter) is: 'configuration'. Exploitation of this vulnerability yields shell access to the remote machine under the 'spiderman' user account.

"value": "La Sophos Web Appliance Remote / Secure Web Gateway server (versi\u00f3n 4.2.1.3) es vulnerable a una vulnerabilidad de inyecci\u00f3n de comandos remotos en su interfaz web administrativa. Estas vulnerabilidades ocurren en MgrDiagnosticTools.php (/controllers/MgrDiagnosticTools.php), en el componente responsable de realizar test diagn\u00f3sticos con la utilidad wget de UNIX. La aplicaci\u00f3n no escapa adecuadamente la informaci\u00f3n pasada en la variable \u0027url\u0027 antes de llamar a la funci\u00f3n de la clase executeCommand ($this-\u003edtObj-\u003eexecuteCommand). Esta funci\u00f3n llama a exec() con entrada de usuario no desinfectada permitiendo inyecci\u00f3n remota de comandos. A la p\u00e1gina que contiene las vulnerabilidades, /controllers/MgrDiagnosticTools.php, se accede mediante un comando incorporado que responde a la interfaz administrativa. El comando que llama a la p\u00e1gina vulnerable (pasado en el par\u00e1metro \u0027section\u0027) es: \u0027configuration\u0027. La explotaci\u00f3n de esta vulnerabilidad da acceso shell a la m\u00e1quina remota bajo la cuenta de usuario \u0027spiderman\u0027."
